Evidence for Late Triassic crustal suturing of the Central and Southern Pamir
Journal of Asian Earth Sciences: X, 2020 The timing of closure of the Paleotethys and Rushan ocean basins and suturing of Gondwanan crustal fragments in the Pamir is not well resolved. Whereas the Central Pamir terrane is generally interpreted to have collided with the Northern Pamir terrane at

An early trend towards gigantism in Triassic sauropodomorph dinosaurs [PDF]
Nature Ecology & Evolution, 2018 Dinosaurs dominated the terrestrial ecosystems for more than 140 Myr during the Mesozoic era, and among them were sauropodomorphs, the largest land animals recorded in the history of life. Early sauropodomorphs were small bipeds, and it was long believed that acquisition of giant body size in this clade (over 10 tonnes) occurred during the Jurassic and

The Anatomical Record, EarlyView.Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Rivista Italiana di Paleontologia e Stratigrafia, 2017 The revision of the material from the Lower Triassic fossil-bearing-nodule levels from northwestern Madagascar supports the assumption that the genus Perleidus De Alessandri, 1910 is not present in the Early Triassic.

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs
The Anatomical Record, EarlyView.Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

The ecology and geography of temnospondyl recovery after the Permian–Triassic mass extinction
Royal Society Open ScienceOne of the mysteries of the Permian–Triassic mass extinction was the subsequent success of temnospondyls. Temnospondyls were key early tetrapods in the Carboniferous and Permian and hardly seem to be ideal pioneers in a tough post-extinction world.

On the age of Early Triassic Tupilakosaurus fauna of Eastern Europe
Известия высших учебных заведений: Геология и разведка, 2015 The composition of Tupilakosaurus fauna is adjusted. Land tetrapod assemblage from the Upper Sukhorechka Subsuite of the Buzuluk Depression is excluded from the fauna.

Regime Shifts in an Early Triassic Subtropical Ecosystem
Frontiers in Earth Science, 2020 The Early Triassic was one of the most remarkable time intervals in Earth History. To begin with, life on Earth had to face one of the largest subaerial volcanic degassing, the Siberian Traps, followed by a plethora of accompanying environmental hazards ...

The Anatomical Record, EarlyView.Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Triassic origin and early radiation of multicellular volvocine algae [PDF]
Proceedings of the National Academy of Sciences, 2009 Evolutionary transitions in individuality (ETIs) underlie the watershed events in the history of life on Earth, including the origins of cells, eukaryotes, plants, animals, and fungi. Each of these events constitutes an increase in the level of complexity, as groups of individuals become individuals in their own right.
